Answer: b. A is acidic, B basic
Explanation: pH 7 is neutral, with equal H+ and OH-
pH is -log(H+ Molar Concentration) and at pH7, H+ and OH- are both at a concentration of 10^-7
A more acidic solution has more H+ than OH-, so it is a higher concentration than 10^-7 and therefore pH lower than 7. Conversely, a pH>7 means a higher concentration of OH- and lower concentration of H+
Considering the definition of pH, the correct statement is option b. A is acidic and B is basic.
You need to know that pH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.
Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:
pH= - log [H⁺]
The scale has values ranging from 0 to 14, with pH 7 being the neutral solution. Solutions with pH less than 7 are acidic and alkaline (basic) those with pH greater than 7.
Then, being the pH of solution A equal to 2, being less than 7, the solution is acidic. On the other hand, the pH of solution B is 8. As the pH is higher than 7, solution B will be basic.
So, finally, the correct statement is option b. A is acidic and B is basic.

In an organism of genotype Aa, half the reproductive cells carry 'A' and half carry 'a'. Mendel called this
Answer:
The correct answer is - Segregation
Explanation:
An organism with the genotype Aa whose half of the reproductive cell or gametes carry A and the rest of the gametes or reproductive cell carries allele a. According to the laws of Mendel, it is the law of Segregation.
In a diploid organism, the genotype of an individual possesses a pair of alleles (50-50 %) for any particular character and is passed one of each to next-generation from each parent.

What organelles are associated with carbohydrates?
Answer:
The only organelle that is associated with carbohydrate synthesis is the Golgi Apparatus.
Explanation:
Hope this helps!
The organelles which are associated with carbohydrates are mitochondria and the endoplasmic reticulum (SER).
What are Mitochondria?Mitochondria may be defined as the double-membrane bound cell organelle which is found in the cytoplasm of the cell. It was first recognized by Kolliker in muscle cells of insects in 1880.
Mitochondria are known as the "Powerhouse of the cell". This is because the energy required for various activities is released by mitochondria in the form of ATP. This organelle also oxidizes the pyruvic acid and forms energy in the form of ATP.
The smooth endoplasmic reticulum is directly associated with carbohydrate metabolism along with other metabolic processes like the synthesis of lipids, detoxification, etc.
Therefore, mitochondria and the endoplasmic reticulum (SER) are the organelles that are associated with carbohydrates.

A) moving
B) shedding.
C) shivering
D) sweating
the answer is shedding because i had the same question on USAtestprep. i thought they would let me view my answers but they didnt. i got and A.
All but one response is a human response to a change in environmental temperatures. That is sweating. The correct option is D.
What is sweating?Sweating is a physiological process that aids in controlling body temperature. Sweating is the expulsion of a salt-based fluid from your sweat glands, which is also known as perspiration.
Four different strategies exist for humans to react to environmental stress: adaptation, developmental adjustment, acclimatization, and cultural reactions.
A genetically based property known as an adaptation has evolved because it aids living things in surviving and procreating in a certain environment.
Sweating can be brought on by changes in your body temperature, the environment, or your emotional state.
Therefore, the correct option is D) sweating.
